Dual-source CTA turns in mixed results for coronary stenoses July 30, 2009 -- Dual-source CT angiography (CTA) achieves a high negative predictive value in excluding coronary artery stenoses in patients with stable coronary artery disease, but the modality is "very limited" in its ability to predict the presence of ischemia, according to a study by German researchers.
COCIR refurb standards could hurt preowned equipment market July 29, 2009 -- The main trade association representing European medical device manufacturers is proposing a set of standards for equipment refurbishing that could make it harder for hospitals to buy preowned equipment from independent firms, according to this Second Opinion by imaging executive Wayne Webster.
New guidelines for resuscitating children recommended July 24, 2009 -- Two new clinical studies used CT to determine that European guidelines for setting the depth of chest compression when resuscitating children may be more accurate than those followed in the U.S. The U.S. guidelines actually could lead to injury in children, researchers say.
Adding PET to 64-slice CT aids detection of heart disease July 20, 2009 -- Adding functional data from PET to 64-slice coronary CT angiography can improve the latter's ability to detect coronary artery disease, overcoming the modality's historic weak point in specificity, according to U.K. researchers.
Prospectively gated coronary CTA nearly equals normal-dose scans July 17, 2009 -- Researchers in Italy report that low-dose prospectively gated coronary CT angiography (CTA) scans are nearly equivalent to retrospectively gated exams in diagnostic accuracy, while reducing radiation dose by up to 72%, according to an article published in the Journal of the American College of Cardiology.
Hybrid FDG-PET, MRI not ready for carotid plaque assessment July 16, 2009 -- Although FDG-PET and MRI can contribute separately to the detection and assessment of carotid plaque, there is a lack of consensus between the two modalities when combined for hybrid imaging, according to U.K. researchers.
More intense hyperthermia better treats cervical cancer patients July 15, 2009 -- When it comes to adding hyperthermia treatment to radiation therapy for advanced cervical cancer patients, hotter and longer treatment is better. That's the conclusion of a Dutch study that found that more intense hyperthermia treatments can extend overall survival.
SPECT may aid in diagnosing early Alzheimer's disease July 14, 2009 -- VIENNA - SPECT may be useful for the very early detection of Alzheimer's disease, according to research reported at the Alzheimer's Association's 2009 International Conference on Alzheimer's Disease.
One-third of breast cancers overdiagnosed, European study finds July 13, 2009 -- Nine years ago, researchers from the Nordic Cochrane Centre roiled the women's imaging community with a study challenging the usefulness of mammography screening. Their new study, which indicates that screening mammography programs contribute to overtreatment of cancers that are actually harmless, is likely to have the same effect.
